Siege of Setenil

The Siege of Setenil was a fifteen-day siege that occurred in 1484 when King Fernando II of Aragon and an army from the Christian kingdoms of Castile, Leon, and Aragon besieged the Emirate of Granada's fortress of Setenil in southern Spain. The terrifying fortress was hard to take with siege engines, so King Fernando decided to use an artillery train provided by his wife Queen Isabella of Castile to take the walls. The siege was a success, and the Christian capture of Setenil paved the way for the conquest of Granada in 1492.
